Opt-in Playwright stealth wrapper for websites the user owns or is explicitly authorized to test. Use only when the user explicitly requests stealth or a documented bot-detection block prevents authorized automation; do not invoke for generic browsing or scraping. Not a CAPTCHA solver.

试用Stealth browser automation using CloakBrowser to bypass bot detection on protected sites. Use when web_fetch fails with anti-bot blocks, CAPTCHA, or access denied errors. Use for scraping reviews, protected pages, or any site that blocks standard Playwright/Puppeteer automation. Not for sites requiring login credentials or solving interactive CAPTCHAs.

CloakBrowser Stealth Fetch
Quick Start
Fetch content from a protected site:
cd ~/.openclaw/workspace/skills/cloakbrowser-stealth/scripts
python3 fetch.py "https://example.com" --wait-ms 3000
Common Patterns
Extract specific elements
python3 fetch.py "URL" --selector "[data-testid='review-title']" --output text
Full page with screenshot
python3 fetch.py "URL" --wait-ms 4000 --screenshot /tmp/page.png --output json
Humanize for aggressive detection
python3 fetch.py "URL" --humanize --wait-ms 5000
JSON output for structured processing
python3 fetch.py "URL" --output json | python3 -c "import sys,json; d=json.load(sys.stdin); print(d['text'][:500])"
When It Works / When It Doesn't
Use CloakBrowser when:
web_fetchreturns 403, bot challenge, or empty body- Target uses standard fingerprint detection (WebDriver, plugins, WebGL)
- Reviews, public listings, non-login content
Don't use when:
- Site requires login (use session cookies instead)
- Interactive CAPTCHA (hCaptcha, reCAPTCHA v2 checkbox)
- IP-reputation blocks (use proxy, see references/config.md)
- Rate-limited after repeated requests
Exit Codes
| Code | Meaning |
|---|---|
| 0 | Success, content extracted |
| 1 | Anti-bot blocked (check output for "blocked: true") |
| 2 | Navigation timeout or error |
| 3 | Script/dependency error |
